Diesel
Diesel must fulfil the EN 590 or JIS K2204
standards.
Diesel engines are sensitive to contaminants,
such as excessively high volumes of sulphur
particles for example. Only use diesel fuel from
well-known producers. Never use diesel of
dubious quality.
At low temperatures (-40 °C to -6 °C), a paraffin
precipitate may form in the diesel fuel, which
can lead to ignition problems. Special diesel
fuel designed for low temperatures around
freezing point is available from the major oil
companies. This fuel is less viscous at low tem-
peratures and reduces the risk of paraffin pre-
cipitate.
The risk of condensation in the fuel tank is
reduced if the tank is kept well filled. When
refuelling, check that the area around the fuel
filler pipe is clean. Avoid spilling fuel onto the
paintwork. Wash off any spillage with deter-
gent and water.
IMPORTANT
Only ever use fuel that fulfils the European
diesel standard.
1 Diesel fuel may contain a certain amount of RME, but further amounts must not be added.
IMPORTANT
Diesel type fuels which must not be used:
special additives, Marine Diesel Fuel, fuel
1
oil, RME (Rape Methyl Ester) and vegetable
oil. These fuels do not fulfil the requirements
in accordance with Volvo recommendations
and generate increased wear and engine
damage that is not covered by the Volvo
warranty.
IMPORTANT
The sulphur content must be a maximum of
50 ppm.
Empty tank
After stalling due to fuel shortage the fuel sys-
tem needs a short time to perform a check.
Proceed as follows before the engine is
started:
1. Fill at least 5 litres of diesel in the fuel tank.
2. Insert the remote control key in the ignition
switch and turn to key position II (see
page 136).
3. Wait for about 1 minute.
4. To start the engine: Depress the brake and/
or clutch pedal, and turn the remote control
key to start position III.
11 Specifications
Draining condensation from the fuel filter
The fuel filter separates condensation from the
fuel. Condensation can disrupt engine opera-
tion.
The fuel filter must be drained at the intervals
specified in the Service and Warranty Booklet
or if you suspect that the car has been filled
with contaminated fuel.
IMPORTANT
Certain special additives remove the water
separation in the fuel filter.
Diesel particle filter (DPF)
Diesel cars may be equipped with a particle fil-
ter, which results in more efficient emission
control. The particles in the exhaust gases are
collected in the filter during normal driving. So-
called "regeneration" is started in order to burn
away the particles and empty the filter. This
requires the engine to have reached normal
operating temperature.
Regeneration of the filter takes place automat-
ically at an interval of approximately 300–900
km depending on driving conditions. Regener-
ation normally takes between 10 - 20 minutes.
It may take a little longer at a low average
